chatterbox URL tracker, how do i make it do this? Options

[curlyred]

u know how theres that code for screen name tracking on the chatterbox?
and how the code makes it so when u click out of the name box it replaces what u put in it with your screenname? well i want to do the same thing w/ the url box but i cant figure out how (like if u edit the URL it will automattically replace it w/ the real one)...
could someone tell me how to edit that code to do that?

thanks...
